Ampex Tape-Type List Ampex Tape-Type List Compiled by Scott Dorsey, NASA Langley Research Center This list started out as a response to the huge number of people asking questions about surplus instrumentation tape, developed into a short description on identifying Ampex tapes, and then developed into an attempt at categorizing all Ampex tapes made. This list is far from complete but is a good beginning: Note: All tapes backcoated unless otherwise indicated NB= Non-Backcoated LNER= Low Noise Extended Range LNHO= Low Noise High Output ----------------------------------------------- 021-- 1 mil rejected NB acetate tape (sold as Shamrock) (early 60s) 031-- 1.5 mil rejected mastering tape (maybe 406, 456, etc. depending on batch) (Was available in 2500' pancakes as well as 7" reels in 1983) 041-- 1 mil version of 031 in 7" only 051-- 0.5 mil rejected NB acetate tape (sold as Shamrock) (early 60s) 101-- Betamax half-inch videocassette (intro before 1978) 102-- VHS videocassette (late seventies) 142-- Helical 2" format video tape for VR-660/1500 (1962-?) 144-- Transverse scan video tape (1964-?) for quad-format machines 145-- Helical 2" formulated for VR-660/1500 video recorders (1966-?) backcoated 147-- A-format tape formulated for VR-7000 video recorders (1965-?) 148-- High Band 2" video tape (B&W) 161-- 1" videotape (1968-?) 163-- 1/2" helical scan industrial videotape (1968-?) 164-- 1/2" helical scan videotape for color use 165-- 1" videotape for IVC 600/800 series recorders 167-- U-Matic videocassette (replaced by 187/197) (late seventies, sold in 83) (Sometimes this is labelled KCA-xx where xx indicates running time) 174-- 1/2" helical scan industrial videotape (1970s?) 175-- 2" Quad tape (backcoated) replacing 144 (sold until 1990) 187-- U-Matic videocassette (Sometimes this is labelled KCA-xx where xx indicates running time) 188-- Older Beta videocassette 189-- VHS videocassette, NB (discontinued 199x?) 190-- 1" IVC/Sony format videotape (1983) 192-- 1" videotape (1970s) (replaced by 196) 194-- 1/2" helical scan industrial videotape (1970s through 1983) 196-- 1" B-format helical videotape (comes in two versions, earlier chrome later cobalt oxide), wound oxide out. 197-- U-Matic 3/4" videocassette (coexists with 187, better quality tape) 198-- Beta videocassette (oxide) (replaced by 208) (1987-??) 199-- VHS videocassette, NB (? to sometime between 1990 and 1995) 208-- Betacam 1/2" broadcast videocassette (oxide, not metal) (changed to BC in 1998) 211-- 1.5 mil NB Irish ???

  • Will Sonyâ•Žs Fourth Playstation Lead to a Second Sony V. Universal?
    WILL SONY’S FOURTH PLAYSTATION LEAD TO A SECOND SONY V. UNIVERSAL? † SETH ASCHER ABSTRACT Sony has included a “share” button on the next version of their popular PlayStation video game system. This feature is meant to allow players to record and share videos of their gameplay. This service shares similarities with the controversial “record” button that Sony included with its Betamax players over thirty years ago. The Betamax player was the subject of the landmark case Sony v. Universal, a foundational case for the modern application of copyright law to new technology. This Issue Brief examines how this “share” feature would fare under the framework laid out by Sony v. Universal and other evolutions in copyright law. INTRODUCTION On February 20, 2013, Sony announced their newest videogame system, predictably named the PlayStation 4.1 Chief among its new features is the share button displayed prominently on its controller.2 Microsoft’s newest offering also has a similar feature.3 Pressing the share button will allow a player to post images or videos of their gameplay to the internet, sharing them with their friends and complete strangers.4 The PlayStation 4 even buffers the last few minutes of gameplay so that a player can share their gameplay video after the fact.5 Sony’s intention is to provide an easy way for players to share images and videos online. Copyright © 2014 by Seth Ascher. † Duke University School of Law, J.D. 2014. 1 Video of the press announcement is available on numerous websites.

  • Digital Audio Basics
    INTRODUCTION TO DIGITAL AUDIO This updated guide has been adapted from the full article at http://www.itrainonline.org to incorporate new hardware and software terms. Types of audio files There are two most important parameters you will be thinking about when working with digital audio: sound quality and audio file size. Sound quality will be your major concern if you want to broadcast your programme on FM. Incidentally, the size of an audio file influences your computer performance – big audio files take up a lot of hard disc space and use a lot of processor power when played back. These two parameters are interdependent – the better the sound quality, the bigger the file size, which was a big challenge for those who needed to produce small audio files, but didn’t want to compromise the sound quality. That is why people and companies tried to create digital formats that would maintain the quality of the original audio, while reducing its size. Which brings us to the most common audio formats you will come across: wav and MP3. wav files Wav files are proprietary Microsoft format and are probably the simplest of the common formats for storing audio samples. Unlike MP3 and other compressed formats, wavs store samples "in the raw" where no pre-processing is required other that formatting of the data. Therefore, because they store raw audio, their size can be many megabytes, and much bigger than MP3. The quality of a wav file maintains the quality of the original. Which means that if an interview is recorded in the high sound quality, the wav file will be also high quality.

  • Media Draft Appendix
    Media Draft Appendix October, 2001 P C Hariharan Media Historical evidence for written records dates from about the middle of the third millennium BC. The writing is on media1 like a rock face, cave wall, clay tablets, papyrus scrolls and metallic discs. Writing, which was at first logographic, went through various stages such as ideography, polyphonic syllabary, monophonic syllabary and the very condensed alphabetic systems used by the major European languages today. The choice of the medium on which the writing was done has played a significant part in the development of writing. Thus, the Egyptians used hieroglyphic symbols for monumental and epigraphic writing, but began to adopt the slightly different hieratic form of it on papyri where it coexisted with hieroglyphics. Later, demotic was derived from hieratic for more popular uses. In writing systems based on the Greek and Roman alphabet, monumental writing made minimal use of uncials and there was often no space between words; a soft surface, and a stylus one does not have to hammer on, are conducive to cursive writing. Early scribes did not have a wide choice of media or writing instruments. Charcoal, pigments derived from mineral ores, awls and chisels have all been used on hard media. Cuneiform writing on clay tablets, and Egyptian hieroglyphic and hieratic writing on papyrus scrolls, permitted the use of a stylus made from reeds. These could be shaped and kept in writing trim by the scribe, and the knowledge and skill needed for their use was a cherished skill often as valuable as the knowledge of writing itself.

  • Videotape: Hardware, History and Applications
    VIDEOTAPE: HARDWARE, HISTORY AND APPLICATIONS Carole 0. Bell and Patricla A. Maetick In recent years, folklorists have begun to raco~nlzeand udllze visu4trCdir ao reeearch and communicative toolr. In 1967, Ralph Rinzler's film work was shown at the Amcrican Folklore Society meetings. Subsequently, films by Bess Lomax Hawes, William Ferris and Carl Fleiechhauer have demonstrated the applicability and importance of visual communication to the study of folklore. In general, however, folklorists have been reluctant to adopt this form of communication. They admire the research footage or fiaished filmic products of their colleagues, but ignore the implications of such work for future remearch into various aspects of traditional humur behavior, Videotape, a relatively new visual medium, ha^ contributed to an increaeine senee of urgency among visually-oriented social scientists. Technical improvements in recent years allow its consideration as an invaluable tool for folklore research. Portable videotape equipment was widely available by 1970, the year when standardization of this hardware became a reality. Greater numbers of people began to handle the equipment and ta rhare with one another the results of their efforts. With the increaoing availability of videotape recording system came the inevitable camparisens with film. Both are multi-media syetew utilizing two channels of trans- mission and reception of information, hopefully in an integrated manner. Yet, they are not the same. The initial distinction is the quality of realneee which video displays. Somehow, it is easier to reopond to the image captured on videotape; the content of the tape meem less removed from the present than that of film.
